I have the answer(1.96 N) i just don't know how my friend got this answer...
so the question was:
A cart(500g) is attached to a hanging mass(200g) over a pulley. Calculate it's magnitude(size).
I've done this kind of problem before. I just forgot how to do it.

The only force in the rope is due to the masses attached to it. Since the cart has more mass and the two are connected across a pulley, the cart will drop to the ground. Three hundred grams of the cart's mass will rest on the ground. The remaining 200 grams will oppose the force in the rope produced by the 200 gram hanging mass
The force in the rope is simply the mass (0.2 kg) times the gravitational acceleration 9.8 m/sec^2
F = MA
F = 0.2 kg * 9.8 m/sec^2 = 1.96 Newtons
